Definitions

  • the invention relates to a lighting device according to the preamble of claim 1.
  • Discharge lamps have the advantage over incandescent lamps a significantly higher light output or economy. There is a ballast for the operation of discharge lamps and an ignitor is required, of which the Ignitor the necessary for starting the gas discharge Provides ignition voltage while the ballast the lamp current after the discharge lamp has been ignited their operation is limited.
  • the ignition voltage must match the resistance in the discharge lamp overcome and is proportional to the prevailing gas pressure is. It can be up to 50 kV, but it only has to are briefly present as a high-voltage pulse.
  • Ballasts can be used as choke ballasts or be designed as electronic ballasts, with choke ballasts a robust construction, high operational reliability and easy handling can be achieved. However, they do need relatively large installation space, the lamp tolerances and changes in mains voltage do not compensate and are relative heavy.
  • Electronic ballasts are the same as mains voltage and -frequency fluctuations over a certain range, are less robust and also require space, appropriate cooling devices and cause additional Weight.
  • Ballast and ignitor are usually in the housing the lighting device, i.e. in the vicinity of the discharge lamp housed because of a long cable length too large from ballast and ignitor to discharge lamp Losses occur or an excessive voltage drop occurs, so that no safe operation of the discharge lamp is guaranteed.
  • ballast and Ignitor When connecting the ballast and Ignitor with the discharge lamp becomes the lighting device however very large and unwieldy.
  • From US-A-5 691 603 is the connection of several lighting units known to a central power supply, the one connected to a voltage source Rectifier with downstream smoothing circuit to which an inverter bridge circuit as an ignition circuit for several lighting units is connected, known.
  • One plug of the central power supply is over Fuses to an output transformer of the inverter bridge circuit connected and with a plug connectable, the electrical via a connecting line Connection to the plug socket of a first lighting unit manufactures.
  • This first lighting unit contains a ballast transformer and a series choke and a fluorescent lamp.
  • a through line is provided, which Socket of the first lighting unit via one on the output socket attached to the first lighting unit connects to another lighting unit that also a ballast transformer, a series choke and contains a fluorescent lamp.
  • DE 33 23 930 A1 is a ballast and ignition device for gas discharge lamps fed from an AC circuit known, the power-independent switching elements, namely a rectifier bridge circuit, a current limiting capacitor, a rectifier multiplier circuit and a double-pole, electromagnetic impulse changeover switch in an igniter housing and performance-based Switching elements, namely series-connected Capacities with smoothing capacitor connected in parallel and discharge resistance in one from the igniter housing separate nominal power unit housing united.
  • the ignition part housing and the power section housing can over Plug contacts connected electrically and mechanically be, the discharge lamp with upstream Smoothing inductance at DC voltage outputs of the ignition part housing can be connected.
  • the object of the present invention is a lighting device to create that versatile and also at limited space can be used, if necessary has low weight and volume, a compact, closed design guaranteed, inexpensive to manufacture is and ensures stable, failure-prone operation.
  • discharge lamps are mechanically and electrically detachable are connected to the ballast and ignitor, different and also several discharge lamps at the same time can be operated with a ballast and ignitor.
  • the discharge lamp Since the discharge lamp is physically separate from the ballast Basic ignitor is operated, the discharge lamp regardless of the relatively large and heavy ballast be started and thus has a low weight on and is particularly in confined spaces can be used advantageously. Because of the short distance and the associated short conduction paths between the discharge lamp and external igniter are the transmission and Voltage losses are minimized, so that safe operation of the Discharge lamp is guaranteed.
  • the Connection of discharge lamp and housing of the ballast Basic ignitor realized via an adapter, whereby a fixed and applicable for multiple units Interface between ballast and basic ignitor and Discharge lamp is manufactured.
  • the adapter can be used as a separate Component or in one of the assemblies to be connected be integrated.
  • the external ignitor has an adapter connection has, which is advantageously compatible with the adapter connection of the ballast and Bsis ignitor is.
  • an adapter connection the discharge lamp on both the ballast and Bsis igniter as well as being operated on the external igniter, without structural changes or intermediate pieces required are.
  • the connecting cable has a plug that several sockets of the external ignitor connected can be.
  • An advantageous embodiment of the solution according to the invention is characterized in that the sockets of the external ignitor different orientations or Have orientations.
  • the sockets of the external ignitor different orientations or Have orientations is an orientation towards the direction of light of the lamp and a attached at right angles to the direction of light of the lamp in connection with the possible connector shapes, e.g. straight- Angled plug, as large a number of combination and to have arrangement options.
  • the possible connector shapes e.g. straight- Angled plug
  • sockets and the adapter connections are compatible are so that, for example, several discharge lamps of the external ignitors in different lighting directions can be connected to a ballast.
  • the adapter connection or the plug socket is designed as a bayonet lock, advantageously the bayonet lock a has rotatable contact plate to the mechanical Interlock not to damage the electrical contacts.
  • FIG. 1 shows a schematic representation of an illumination device B with a ballast and basic ignitor 1, to which a discharge lamp 7 is attached.
  • the ballast and the basic igniter are electrical form two separate components, these are called together Ballast and basic igniter 1. Will on one of the two components are referred to separately referred to as ballast 1a and basic igniter 1b.
  • the lighting device differs B by conventional lights a modular structure through which different discharge lamps 7 on a single ballast and basic ignitor 1 can be operated.
  • the adapter or adapter connection 2 2 is such trained that the discharge lamp 7 mechanically fixed the ballast and basic igniter 1 is connected so that an arrangement of the lighting device B on a Tripod or the like is possible.

  • FIG. 2 shows a variant of the lighting device B, at the on the adapter connection 2 of the ballast and ignitor 1 an adapter 3 3 is connected via a Connection cable 4 connected to an external igniter 5 is.
  • the external igniter 5 in turn has an adapter or adapter connection 6, which is connected to an adapter Discharge lamp 7 can be coupled mechanically and via which Discharge lamp 7 electrically with the external ignitor 5 is connectable.
  • an ignitor is relatively small and lightweight can be achieved by combining the external ignitor 5 with the discharge lamp 7 mobility or The area of application of the discharge lamp 7 is only insignificant limited.
  • the direction of light of the discharge lamp 7 indicated by the arrow which means that the external igniter 5 on the back of the discharge lamp 7 is connected.
  • the adapter or adapter connection to the discharge lamp 7 also directly with an adapter or adapter connection of the connecting cable 4 can be coupled, a direct connection of the Discharge lamp 7 with the adapter 3 of the ballast and Base igniter 1 are made without the ignition circuit of the ballast and basic ignitor 1 bridges becomes.
